I bookmarked this page, along with other 9x9 opening pages, to use as a quick reference during 9x9 games. Out of the ones I bookmarked, this page's title makes it easy to click when actually it is not so helpful as it only gives names to specific and perhaps uncommon occurrences in games. I don't know what these names mean and nor is there any discussion on the openings themselves.
Therefore why should this be called "in more depth"?
